used for turning any property value (between “:” and “;”) in
CSS to the <span class="type">GValue</span> needed. For basic types there is already
builtin parsing support, so <code class="literal">NULL</code> may be provided for these
cases.</p>
<p>Engines must ensure property registration happens exactly once,
usually GTK+ deals with theming engines as singletons, so this
should be guaranteed to happen once, but bear this in mind
when creating <span class="type">GtkThemeEngines</span> yourself.</p>
<p>In order to make use of the custom registered properties in
the CSS file, make sure the engine is loaded first by specifying
the engine property, either in a previous rule or within the same
